[Security advisory for CVE-2022-35403] Unauthenticated local file disclosure vulnerability in ServiceDesk Plus MSP

Hi there,

 

This is a security advisory regarding the unauthenticated local file disclosure vulnerability in inline image handling in ServiceDesk Plus MSP, which has been identified and rectified. This affects users of ServiceDesk Plus MSP (all editions) running version 10605 and below.


This issue was reported by our internal security team on our bug bounty portal.

 

Severity: High

 

Impact
This vulnerability allows adversaries to download local files from the server on which ServiceDesk Plus MSP is installed by sending an e-mail to the e-mail address configured in the application with a crafted image URL pointing to the specific file. If the file is present in that location, it gets added as an attachment in the ticket conversation when a technician responds to or when a notification is triggered for the ticket.

 

What led to the vulnerability?
The image's URL was not being processed properly when a technician responded to it or when a notification was triggered for the ticket.


Who is affected?

This vulnerability affects on-premises ServiceDesk Plus MSP customers of all editions using versions 10605 and below.

 

How have we fixed it?

We have added additional checks to process the inline image to avoid the local file disclosure vulnerability.
